Residual voids

Open cut mining practices have historically left open mining pits (referred to as ‘residual voids’) in place at the end of mining. These voids can become pit lakes and can pose ongoing risks that may need to be managed. Voids can also be used to generate opportunities for post-mining uses, including irrigation of crops, provision of stock drinking water, pumped storage hydropower, aquaculture or development of recreational areas.

  • Technical brief, managing water during and after mine rehabilitation, October 2022 (PDF, 520.5KB)
    This technical brief summarises the regulatory and planning considerations for the transition of water rights and water infrastructure from an operational phase of mining to rehabilitation and closure. It also outlines the implications for leading practice as recommendations for support the transfer of water rights, licensing and responsibility for ongoing management of water infrastructure from active mining to a closed mine.
